I have one of those somewhere. It's missing that aluminium (?) insert where the head tube enters the stem.

Can you give me the dimensions for that piece - I think i might see if I can get one machined.

Length & wall thickness should suffice.

Just let me kow if you measured by eye, trusty tape measure, calipers or micrometer

This should do it:

I have a prototype version of that, it clamps onto the steerer at the back with a pair of bolts, doesnt look as slick as that one...

Like this one? Looks pretty slick IMHO:

I think you do need to use it due to the shape of the stem. Bottom of the stem needs to sit flush to the headset/spacers, but the bottom of the stem is all curvy meaning that it won't unless you use the shim type thing, or am I wrong?

You're exactly right. It is essentially a headset spacer integral to the stem design so it will sit flush to the headset.
